Hi Chris , Doing a few changes, got rid of the intercooler and put a smaller radiator in it to make it easier to work on , My mate that helps me with the fab work broke his sternum in a car accident which has slowed things up, hopefully a few weeks and I'm back out there

What was used in a race car with big boost probably won't work well for a street car. They need to be tailored to your specific use. A turbo set that flows to much air can overboost a different sized engine quickly. You need to get a turbo book and learn before buying turbos. Pressure ratios and the turbo maps with the island of peak efficiency. Remember you want to play in right field on the map.

for street use

you want a smaller , quicker spool turbo (s)
as seldom will your street car see 6000 rpm .
(if it does see 6000 rpm often, your nuts!)
I am building a 53 Stude PU, with a 481 cu in BBC,
twin turbo, using a pair of GT45 turbos, and blow thru carb set up.
not a hi dollar set up, but very streetable and affordable.
don't care what kind of HP it will make, just as long as it runs ok, and
is reliable, waste gates will be set at 8psi, so don't expect excessive hp numbers.
running to a 4L80e trans, and Franklin quick change rear end.
engine is a 8.5 comp ratio, steel crank, forged pistons, 4 bolt main, with a
cam ground for turbo use,
I don't have any pics yet, but will as I start assembling every thing.
still working on the truck itself.
